It looks better on the car in your pic than it does with what the vendor posted up as a pic.
I just ended up pulling my rear lower part of the bumper off and got the small 2 piece's painted from the vendor in here for about 400.00 where it has 2 for each side on the car..Robert

Thanks for the feedback guys! 
We build everything from aluminum to handle track abuse, keep it light and 3 times cheaper than carbon fiber. http://www.difflow.com/corvettec7diffuser.html
Also, the Difflow diffuser is seen on the "World's fastest Z06."

No diffuser will do anything until you're well north of 100 mph. If it's designed right you'll get additional downforce at very high speeds. At lower speeds it's purely for looks.

I am not sold on any diffuser whose fins are very thin. If you look at any well made factory diffuser for any AMG/M/GTR etc. the fins are fairly thick.
The diffuser might also need to curve at the either end to conform to the shape of the rear bumper of the C7.

Most diffusers start working at highway speeds depending on the aggression of the diffuser.

Cooling - We have this diffuser on track cars everywhere, including the 1200+ HP Z06 owned by Skip Harmon and he's running 9 second quarter mile times with no heat issues. We also drove a Z51 with our diffuser from CA to MT, no issues with heat/cooling what-so-ever.
Ride - Diffusers don't impact the ride other than increasing stability at high speeds.
Hope this helps!

Not doubting your engineering prowess, but you just dissed two of the best automotive engineering shops. Not a smart move.

If you stick your hand out the window of your car on the highway... you can do 2 things:
1) Let your palm face the wind. What happens? Your arm gets thrown backwards from the wind hitting it.
2) Let your palm face the ground with your fingertips in the wind. What happens? Your hand stays stationary, and even glides forward.
Your palm facing the wind = a thicker diffuser fin.
Your palm facing the ground/fingertips forward = a thinner diffuser fin.
